Delta Pulse

OK i should put the coil on 2-10cm and next adjust by GEB pot and reject ground effect.and i understand your means thanks .

I REPEAT. you have to do:
1. dig a hole in ground. put the brick in it.
2. tune DP on ground, do ground balance. as I wrote above - on clear ground, it means WITHOUT BRICKS, HOT ROCKS, ANY METAL in ground under coil.
3. do test on the brick in ground.

just checked my idea of autoreset... mod is working good.

Hi kt315

Value of C is 47uF ?

Thanks.

[kt315]

hi greylourie, I checked with different values. 47 uF gives for me more clear reset, without retained sound. 33 uF is also, 22 is with retained sound. so 22-33 is at edge.
I could be change also R47 to 200-470k, but checked with 100k finding optimal C value.

hi
Merci . i want add 22mikro tantalum but which is the better , look the pic please , and i certain polarity right ?

i buy metal film res , i want replace R6 ( 1k ) by metal film res .


again thanks .
this is an idea :
can we add discrimination for Dp2 like PSG detector ? add 4053 and .... , it is possible ?

regards

DP with the auto-reset mod.

Thanks for the mod. Auto reset.
Tomorrow I'll try my DP.

Underground metal detector enthusiast I was one from China today saw your production performance is great, you are highly skilled experts, and I hope to get your support and hope you can put electronic circuit diagram of the product send me a copy of my very capable hands hobby electronics production, would like to have a great depth probe pulse induction detector circuit diagram yourself, I hope you can complete my wish, send me an electronic circuit diagram of my own to make a. Whatever the outcome, I have to thank you. China Shandong Linyi I look forward to your reply, my e-mail: [email protected]
'm Looking forward to your technical guidance, I will look forward to your e-mail every day. No matter how the results like I have to thank you very much.

need in help... I try find this type of pot in google and ebay, but do not see.

[kt315]

I see for example this pot, but it is with short shaft. I need with 16-18 mm shaft.

I use words 500k linear plastic D-type shaft, no result.

something near but not the same http://www.ebay.com/itm/New-500K-OHM...3D150471585976

Here are some similar parts. http://www.reichelt.de/6mm-Potis-mon...s&GROUPID=3135

I might still have some but they are marked funny like 50 mb and stuff like that let me look I know old computer screens used to have them I took all from 3 so let me look if I still have them they are yours.

[kt315]

thank you, folks. thinking 500kOhm of this type is hard to find I did hope it is more popular...
----
back to HV diode... I found this diode in electronics trash. will experiment with it...

I think your right all the ones I have are marked m20kb so 20k sorry I thought I had at least one at 500 k I have about 10 that are 20 k

please answer

your testings are absoliutely wrong. do you see in my videos I keep a target, gold ring, in my hand?? NOT. your hand, your body is an antenna,
it accumulates electrostatic charge around everywhere, it explorers electromagnetic field everywhere from electric nets, some kinda re-translator.
so you get a testing with the influence, that is unhonest testing.

hi dear KT315
please see and answer , i wait for you .
